There are two ways to ensure that your live streams work without bottlenecks. You can either use a streaming software encoder or a streaming hardware encoder.
Right now, we will be focusing on hardware encoders.
Software encoders are best suited for beginners because they are easy to set up, cheaper, and mostly automatic.
Hardware encoders are for users who mean business. Twitch streamers use them to ensure uninterrupted hours of live streaming with minimum lags and glitches.
With this article, we will try and help you understand the ins and outs of hardware encoders.
But before we get to all that, make sure you read up on the following terms to fully understand the information in this article.
Streaming Encoder Hardware – Technical Terms
- IP(Internet Protocol)- IP and IP address are two different things. IP is a set of rules and protocols that facilitate data transfer over the internet. The IP address helps locate your device in the internet world for communications and data transfer.
- CDN(Content Delivery Network)- A CDN is a distribution network spread across the internet that delivers the content from one IP to another.
When a user clicks on a live stream, the CDN delivers the content from the originating IP to the viewer’s IP.
- Encoding- The word encode means converting raw data into code so computers can understand and process it.
Similarly, a streaming hardware encoder will capture and compress a live stream’s video and audio, so it can travel through the internet.
- Codecs- An encoder compresses live streaming content, and codecs are the methods/formats of compressing content. Audio, video, images, and text- all content requires different types of codecs.
For live streaming, there is a set of new-gen codecs. The most notable ones are MJPEG, H.264, HEVC, VP9, and AV1.
- Streaming Protocols- After codecs compress the data that is to be transferred, streaming protocols ensure transportation of content, using numerous CDNs. The various streaming protocols perform the task for different streaming needs.
- Bitrate- Bitrate is the rate at which your stream’s data bits are processed and transferred within a given time. A higher bitrate means better streaming. Along with encoder hardware, bitrate also depends on device hardware and the internet connection.
Different streaming platforms have different bitrate requirements, and that’s where the ‘auto bitrate’ feature of a streaming hardware encoder comes in handy.
What is a Streaming Hardware Encoder?
Amid the Covid-19 pandemic, live streaming viewership doubled on major platforms like Twitch, YouTube, and Periscope.
So streamers, along with maintaining content quality, had to ensure stable and high-quality streams. To do that, streamers looked to hardware encoders.
A streaming hardware encoder is an independent device that connects to your computer/laptop/streaming device and drastically improves your live stream’s video and audio quality.
These devices ensure that the viewers receive the live stream in the correct format at the best possible quality regardless of their location and device.
But, while ensuring quality, it’ll also leave its mark on your wallet. A decent hardware encoder will cost you around 300 bucks.
How does a Hardware Encoder Work?
Here’s what a hardware encoder does:
- Connects to a computer/streaming device using HDMI, SDI, or DVI.
- Captures the audio and video signal.
- Encode and convert into the correct format automatically.
- Transfer that file to every viewer over IP and CDN.
It might seem simple, but it is one of the most complex parts of live streaming, that’s why amateur streamers prefer software encoders.
Why use a Hardware Encoder?
You need a top-quality video encoder to stream on the best live streaming platforms, and a hardware encoder is your best bet, period.
Yes, a software encoder is cheaper, but it doesn’t come close to a hardware encoder in terms of performance.
Both software encoders and hardware encoders do a decent job at creating and maintaining high-quality streams, but hardware encoders are a tad better. One reason is the dedicated hardware, which allows hardware encoders to do the following.
- Higher Video Resolution
Hardware encoders can achieve as high a bitrate as 30,000 kbps. That means, with the right hardware, you can stream content in 4K or 8K and 60 fps or higher.
- Low CPU Usage
Because hardware encoders have their own boards and a dedicated GPU, the strain of your CPU decreases. On the other hand, while using a software encoder, that strain increases.
- Multi-Streaming
Newer software encoders are integrating this feature, but a hardware encoder is the better choice to multi-stream your content.
Software encoders will use up more CPU power whereas hardware encoders’ dedicated GPU can handle that without compromising the performance.
With a hardware encoder like Teradek VidiU, you can simultaneously stream to all major streaming platforms.
- MultiCam Setup
Hardware encoders allow multiple camera setups.
In other words, a hardware encoder can simultaneously encode and compress the content being captured from one or more cameras.
To summarize, a hardware encoder provides all the power for a complete and professional live streaming setup.
So, instead of using software encoders and spending buckets of money on computer upgrades, it’s better to go for a hardware encoder.
